Incorrect encoding

Sample map file used to reproduce issue: https://github.com/frosty-dev/white-dream-main/blob/master/_maps/map_files/BoxStation/BoxStationWhite.dmm

Incorrect mapfile reader result:

• Original: name = "O2 в Чистоту"
• Saved: name = "O2 ?? ??????????????"
• Incorrect name in StrongDMM rendered context menu:

Probably dupe of #15.

I think the main issue is with the reader, causing reader read the map in non-UTF-8 (probably ASCII) and saving in non-UTF-8 format. Yes, 513 uses UTF-8.
